B&W UV Filters Question

Hello everybody.

On my lenses I always used B&W UV MRC 010 filters. Now that I've changed lenses (and camera), I  look around for B&W filters. Maybe the same again, but I also read about the B&W MRC Nano Pro filters. Is there anyone who has experiences with these (or both?). What's your experience? I'm also considering to use the 007 clear series instead of the 010. Any experiences here? Recommendations maybe?

Thnxs for all input!
